HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 791, 658, 14 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 791, 658, 14 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 680, 791, 658, 14 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 680, 791, 658, 14 is 1.
HCF(680, 791, 658, 14) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 791, 658, 14 is 1.
Step 1: Since 791 > 680, we apply the division lemma to 791 and 680, to get
791 = 680 x 1 + 111
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 111 and 680, to get
680 = 111 x 6 + 14
Step 3: We consider the new divisor 111 and the new remainder 14, and apply the division lemma to get
111 = 14 x 7 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 680 and 791 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(111,14) = HCF(680,111) = HCF(791,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 1, we apply the division lemma to 658 and 1, to get
658 = 1 x 658 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 658 is 1
Notice that 1 = HCF(658,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 14 > 1, we apply the division lemma to 14 and 1, to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 14 is 1
Notice that 1 = HCF(14,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 680, 791, 658, 14?
Answer: HCF of 680, 791, 658, 14 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 680, 791, 658, 14 using Euclid's Algorithm?
Answer: For arbitrary numbers 680, 791, 658, 14 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
